It's well known that males, especially American, are to put it mildly not so great at managing their emotions. after a long period of extreme stress, one sign they are having problems is with something called "cute aggression"

Been over 20 years since I got out but I remember mentioning it in passing to the woman I was dating at the time who was a licensed therapist. She was insistent that a noticeable amount of post service and recently deployed men (and some women) experienced this for a time.

After a year or so it stopped happening without needing treatment which is why I am guessing it doesn't get much if any attention. Personally I find it funny remembering having this shockingly visceral hate response to seeing the dough boy or that fucking fabric softener animated teddy bear.
